Sigma Art 15mm f/1.4 DG DN Diagonal Fisheye
Why we recommend this ▼
Its f/1.4 maximum aperture pairs with a 15mm full-frame fisheye design to deliver a 180° angle of view and a 21-element optical path with aspherical and ED glass for sharp, high-contrast images. The weather-sealed, 1360g build and fast, near-silent HLA autofocus provide dependable outdoor handling, while the 11-blade diaphragm ensures smooth bokeh. This lens is best for astrophotographers needing bright low-light capture and creative portraitists exploiting its dramatic, distortion-filled perspective for environmental shots.
